About The Cover

COVER Part of the cylindrical Compact Muon Solenoid particle detector descends to a hall 100 meters underground at the European particle physics laboratory CERN. The detector will capture the hail of particles produced when CERN's Large Hadron Collider smashes protons at unprecedented energies. A special News report beginning on page 1652 profiles the new collider. Photo: Maximilien Brice, CERN
